As technology develops, school students who are off class may have no fear of too much absence from class. A small robot may help those children recovering from a long-term illnesses in the hospital or at home. These children may feel isolated from their friends and classmates. The robot takes their place at school. Through the robot, the children can hear their teachers and friends. They also can take part in class from wherever they are recovering.

    Anyone who has had a long term illness knows that recovering at home can be lonely. This can be especially true of children. They may feel left out. Now these children may have a high-tech friend to feel less alone. And that friend is a robot. The robot is called AV1. AV1 goes to school for a child who is at home while recovering from a long-term illness. And the child's school friends must help. They carry the robot between classes and place the robot on the child's desk.

    A Norwegian company called No isolation created the robot. The co-founders of No Isolation are Karen Dolva and Marius Aabel. Dolva explains how the robot AV1 works. She says, from home, the child uses a tablet or phone to start the robot. Then they use the same device（设备）to control the robot's movements. At school, the robot becomes the eyes, ears and voice of the child. The child can take part in classroom activities from wherever she/he is recovering-whether at home or from a hospital bed. The robot is equipped with speakers, microphones and cameras make communicating easy.

The situation is that familiar — deadlines are approaching, time runs out, disorder and confusion fills the day. The feeling is just as familiar — a slightly faster heart rate, and shortness of breath. Yes, it is panic time.

    It's too late to kick yourself with "I should have started on this sooner." or "It was a mistake to accept this tight deadline." The only thing left to deal with the situation is to panic more efficiently.

    ① Focus.

Panic happens when you are on an overload — too many things to do, too much pressure, too little time. But if you focus on the tasks that you need to take care of, and line them up in a logical list, you can have better control of a highly stressful and wild situation.

    ② Get rid of distractions.

    Time wasters and unnecessary activities are the last things you need during this time. Let everyone know you are on panic mode and should not be disturbed unless it is an emergency.

    ③ Watch your time.

    Don't be too engaged in one detail so that you reduce your timing for the other important details. Mind the time and deal with each task so that you can finish all of the required activities sufficiently.

    Try to solve a panic situation as quickly as you can so that you can rest and get back your energy and strength for the next one.

    China will build a comprehensive (综合性的) network to detect (检测) pollution of the land, sea and air by 2020, employing satellites, drones(无人机)and remote sensors to monitor the environment.

    The national leadership agreed to the network plan in July, saying the government will lead the monitoring, share information among departments and regions, and be held accountable (追究责任) if violations (违规行为) are found, the Ministry of Environmental Protection said on Tuesday.

    Satellites, a major tool for monitoring air pollution, will receive a boost (大力发展)  this year. The ministry said it will accelerate research on two atmospheric environmental monitoring satellites.

    The ministry will improve a remote sensor network, guided by the goals of the 13th Five-Year Plan (2016-2020), which is scheduled to be released at the end of this year, according to the ministry's Environmental Supervision Department.

    Remote monitoring has played a bigger role in locating pollution sources. Drones helped authorities locate polluted areas in the Tengger Desert in northern China and identify scattered summer straw burnings.

    Hebei province, which has a serious air pollution problem, has cooperated with the ministry's Satellite Environment Center to conduct monitoring from satellites and monitoring stations since January last year.

    "We used the data from the center's satellites to forecast the movement of smog during the Asia-Pacific Economic Cooperation meetings in November, "Zhang Feng, an engineer in the Environmental Supervision Department of the provincial environmental watchdog, said on Tuesday.

    Data collected from monitoring stations helped authorities provide accurate forecasts on hazy days during that period, he said.

    Since the first Earth Day in 1970, Americans have gotten a lot “greener” toward the environment. “We didn't know at that time there even was an environment, let alone that there was a problem with it,” says Bruce Anderson, president of Earth Day USA.

    But what began as nothing important in public affairs has grown into a social movement .Business people, political leaders, university professors, and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many, many times,” says Gaylord Nelson, the former governor from Wisconsin, who thought up the first. According to US government reports, emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of “Green thinking” has become part of practices.

    Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.

    Twenty –five years ago, there were hardly any education programs for environment. Today, it's hard to find a public school, university, or law school that does not have such a kind of program. “Until we do that, nothing else will change!” say Bruce Anderson.

    We humans love to stare into our smart devices. We gaze for hours—about 10 hours and 39 minutes a day—at our computers, smartphones, tablets and televisions. Is all this staring bad for us? It might be, mainly because as we stare at our devices we are exposing ourselves to blue light.

    Blue light is a type of electromagnetic radiation with a very short wavelength that produces a high amount of energy. While it's true that light can damage our eyes under certain circumstances, there's no scientific evidence suggesting that blue light is harmful to our eyes. But many people still think it is, which is why blue light—blocking glasses are so popular. So do the glasses work?

    “Everyone is very concerned that blue light may be causing damage to the eye, but there's no evidence that it may be causing serious damage, "Dr. Rahul Khurana, clinical spokesman for the American Academy of Ophthalmologists, told Business Insider.

    Blue light exposure is nothing new. In fact, the sun is the largest source of blue light. Moreover, blue light is also present in LED light. But if blue light isn't harmful, then why are we constantly rubbing our eyes when we're looking at our screens? The answer is eyestrain(眼疲劳):More than 60 percent of people experience eye problems associated with digital eyestrain. And blue light, it seems, isn't the cause. Instead, our eyes are so strained because most of us blink less when we stare at our digital devices. So if eyestrain is the real issue, blue light-blocking glasses are probably of little use.

    Sports accounts for a growing amount of income made on the sales of commercial time by television companies. Many television companies have used sports to attract views from particular sections of the general public, and then they have sold audiences to advertisers.

    An attraction of sports programs for the major U.S. media company is that events are often held on Saturday and Sunday afternoons — the slowest time periods of the week for general television viewing. Sport events are the most popular weekend programs, especially among male viewers who may not watch much television at other times during the week. This means the television networks are able to sell advertising time at relatively high prices during what normally would be dead time for programming. Media corporations also use sports to attract commercial sponsors that might take their advertising dollars elsewhere if television stations did not report certain sports. The people in the advertising departments of major corporations realize that sports attract male viewers. They also realize that most business travelers are men and that many men make family decisions on the purchases of computers, cars and life insurance.

    Golf and tennis are special cases for television programming. These sports attract few viewers, and the ratings(收视率) are unusually low. However, the audience for these sports is attractive to certain advertisers. It is made up of people from the highest income groups in the United States, including many lawyers and business managers. This is why television reporting of golf and tennis is sponsored by companies selling high-priced cars, business and personal computers, and holiday trips. This is also why the networks continue to carry these programs regardless of low ratings. Advertisers are willing to pay high fees to reach high-income consumers and those managers who make decisions to buy thousands of "company cars" and computers. With such viewers, these programs don't need high ratings to stay on the air.
